[0036] The flipping assembly 4 includes a straightening platform 45 fixedly mounted on one side of the two slides 52 near the feeding conveyor belt 54. The two straightening platforms 45 support the two ends of the hub shaft tube. A conveyor belt 46 is rotatably mounted on the side of the straightening platform 45 near the mounting frame 2. The conveyor belt 46 has a certain degree of tightness, so that when materials are placed on the conveyor belt 46, the driving shaft of the conveyor belt 46 can drive the conveyor belt 46 to rotate, and the conveyor belt 46 also plays a role in limiting and stabilizing the hub shaft tube. Under the obstruction of the triangular flipping plate 410, the conveyor belt 46 is convenient for driving the hub shaft tube to rotate on the straightening platform 45, so that the infrared detector 48 can detect the degree of bending of the hub shaft tube, and the conveyor belt 46 is convenient for driving the hub shaft tube to move to a position where the straightening block 3 applies pressure for straightening, and the straightening platform 45 is away from the infrared detector 48. A triangular flip plate 410 is rotatably installed on one side. The triangular flip plate 410 not only plays the role of intermittently flipping the hub shaft tube for unloading, but also plays the role of limiting the position of the hub shaft tube on the straightening platform 45. A mounting groove 411 is provided on the side of the straightening platform 45 away from the mounting frame 2. A full gear 414 is rotatably installed in the mounting groove 411. A first motor 47 is fixedly installed on the side of the straightening platform 45 away from the conveyor belt 46.

The inclined plate 42 is a guide plate with a certain elasticity, which is used to buffer the hub axle tube being unloaded, and plays a role in buffering the gravity of the hub axle tube. In order to avoid damaging the surface of the hub axle tube during the unloading process as much as possible, a plurality of buffer strips 43 are fixedly installed on the top surface of the inclined plate 42. The buffer strips 43 play a role in slowing down the rolling speed of the hub axle tube on the inclined plate 42. A buffer sponge 44 is fixedly installed on the inner bottom wall of the collection box 41. The buffer sponge 44 plays a role in protecting the hub axle tube, facilitating the self-rotation detection of the hub axle tube, and facilitating the flipping and unloading of the hub axle tube, facilitating the unloading operation, avoiding the situation of manual unloading as much as possible, and helping to improve the working efficiency of the flipping and unloading device, and helping to improve the working efficiency of the straightening device.

The output end of the third motor 59 slides through the slide 52 and is fixedly installed on the driving shaft of the loading conveyor belt 54. The third motor 59 plays the role of driving the loading conveyor belt 54 to move, which is convenient for feeding the straightening table 45 and flexibly adjusting the distance between the two loading conveyor belts 54 according to the length of the hub shaft tube. The adjustment operation is convenient, which is conducive to improving the adjustment ability of the device, improving the flexibility and practicality of the device, and improving the straightening efficiency of the device.

At the same time, the conveyor belt (46) is started to drive the hub shaft tube to rotate on the straightening table (45) for detection, and then the moving component (6) is started, so that the moving component (6) drives the straightening block (3) to move to the bent position on the hub shaft tube, and then the hydraulic telescopic rod (66) is started to apply pressure to the hub shaft tube for straightening, so that the straightened hub shaft tube falls into the collection box (41) under the turning of the triangular turning plate (410), and at the same time, the hub shaft tube first falls onto the inclined plate (42) and then falls onto the buffer sponge (44) for collection.
